The value of art, like anything else is a mishmash.
I wouldn't pay $100k for Dogs Playing Cards, even though I kinda like the painting - it's amusing to me. You couldn't PAY me to eat a McDonald's, but I'll spend a fortune at a top NYC restaurant where the space on the plate is more than the footprint of the actual food and I'll be snobby about it too. I'll complain about the $2.40 per gallon gas which drives a machine that was engineered and manufactured using even more engineered machines and processes and delivered to me via a logistical network of processes and thousands of people across several continents, but how many times have I bought coffee at $339.20 per gallon, grown and picked by Juan Valdez and distributed to the local Starbucks? And what about movies? I'm sure the women (from my experiences) LOVE the English Patient and 'value' it, whereas we know just how much men love this 'chick flick'.
You all get the point. To make absolute statements that I've read here is just funny.
Art.
